hello gamer here...
i would like to share with you guys, i tried google the trick but i think this is new...

modern pc nowadays are capable to carried out high resolution right...
but DOTA can't carry out, the higher is 1280 x 1024...

there are trick using registry which for sure you guys know...
some you guys succeed but MOST didn't...



here what i found...

after you guys edit the registry key which suit yur resolution, actually the moment you open yur game its already on the choosen resolution....
don't go to OPTION > VIDEO...
coz it will revert back to normal...
just leave it with it default resolution



how to me know...
proceed to yur game, go to VIDEO OPTION inside the game...



there you go...
it already on yur desired resolution...

hope i'm not slowpoke...
if yes, just want to share...



regard...

me will post in my blog later for your references later....
